I have hardwired my X50 to one of my bulbs next to the sunroof. Its working OK, i havent noticed any issues so far. my x50 is configured for V, so it shows current voltage. I have noticed that it will jump from 12V to 13, 13.5V and down to 11V. It never stays at 12V. I thought it would stay at 12V all the time. So then i swiched from hardwired to basic escort power cable and doesnt stay at 12 also. It goes to 14, 13.5, 13. 12.5V. Am I the only person to have this problem or there are alot of you out there ?
